e PECHICATION forming part of Letters Patent No, 391,301, dated October 16. 1888.

A pplieation filed June 20, IESS.

To @ZZ whom, it may concern:

Be it known that we, LOYAL Y. COCHRAN, of Allegheny, in the county of Allegheny, State of Pennsylvania, and WILLIAM J. LIND- SAY, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Furnace Fuel- Feeders; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in furnace fuel-feeders; and it consists in certain features of construction and in combination of parts,hereinafter deseribed,and pointed out in the claims.

In the accompanying drawings, Figure l is a view in perspective. Fig. 2 is an enlarged detail, hereinafter described.

A represents a dust and fuel collector, the same being supplied through a tube, A. rlhe eollectorhas usnallyahopper or funnel shaped bottom, A, terminating in a tube, A3, and the latter branches into tubes a and a. Tube a leads into a receiving and storing room, B, where the surplus shavings are received and stored for the time being until they may be disposed of. lubercil leads to the furnace or furnaces for supplyingA the saine with fuel. A valve, b, located in the crotch of the pipes controls the distribution of fuel through the respective pipes cl. and a. In the upright position of the valve shown in solid lines about an equal quantity of shavings will be discharged through the two pipes. In practice,by manipulating this valve a sufficient quantity of fuel Y is supplied to the furnace and the balance of the fuel discharges into room B.

Pipe amay have as many branches as there are furnaces or as there are compartments or fire-boxes to be supplied. In the present instance two such branch pipes, C C, are shown with valve c, for controlling the discharge of these pipes, this valve being substantially the same as the one j ust described.

Pipes C have hinge-joints C', so that the lower sections thereof may be turned back and up out of the way, as shown at the left hand.

Serial No. 277,631. (No model.)

lhelowerhorizontal seetionsofpipeCeonnect, respectively,with nozzles D, the latter leading into the respective furnaces.

E is a steam-pipe leading from the boiler, pipe E having branches E', corresponding and connecting with pipe C. The lower sections of pipes E lead,and discharge into the center of the contiguous pipes C, as shown at c,-sueh discharge being in line with nozzles D.

rlhe dust and shavings in these nozzles are blown into the furnaces by the steam-blast,the latter also causing a suction through pipes C, that draws the shavings along down these pipes. .Pipes Ef have joints e, the axis of which respectively is coincident with the aXis of the hinge of the adjacent pipes C,to which such pipe, E', is attached. The joint in each pipe E may serve, also, as a valve, and shuts off steam when such pipe is turned back and upward out of the way. There are several varieties of such Valves that are well knownfor instance, the valve shown in Fig. 2. When the pipe is in its depending position connecting with the nozzle D, the valve is open, admitting a full head of steam into the said nozzle. The steam-blast, by reason of its discharging into the furnace, distributes the fuel and aids combustion, and is in every way advantageons.

Vith the construction shown, where two or more boilers are employed, any one of the boilers and connected furnaces may be cutout of the fuel distribution by simply turning back the-pipes, as aforesaid. Cords F and pulleys f are usually arranged for drawing back aud holding the different swinging sections of the fuel-pipe.

In practice it is frequently necessary to make so many elbows in the fuel-pipe that there is difficulty in feeding the fuel through such elbows by ordinary means. In such case we provide nozzles connected with the steanrpipe or with branches thereof, these nozzles being located so as to apply a steam-jet inside the fuel-pipe at either side of the elbow, (see nozzles e and 62,) such steam-jets, of course, discharging in the direction that the fuel is to travel in reaching the furnace. Vith such arrangement of steamjets at the corners or elwith such jointed section of the fuel-pipe, the

axes of such joints being coincident, and the steam-pipe discharging into the fuel-distributing pipe, substantially as set forth.

3. The combination, with a storing-room, a dust and shavings collector, and two or more furnaces, of pipes divergng from a common point at thelower end of the collector, one of said pipes leading to the storing-room and the other into jointed fuel-pipes, said pipes leading to furnaces, and steam-pipes connected with such jointed sections of the pipes, the axes of such joints being coincident, and the steam-pipe discharging into the fuel-pipes, substantially as set forth.

In testimony whereof We sign this specification,in the presence of two witnesses, respectively this 16th day of April, 1888, and this 21st day of April, 1888.

Lindsay instead of Villial say, and that the said Letters Patent should be read with this correction th the same may conform to the record of the case in the Patent Office.
